MAGNIMBUS ATOMIC TOTAL-FIELD MAGNETOMETER

Ultra-sensitive airborne integrated magnetometer system powered by QuSpin QTFM Gen-2 atomic total-field magnetometer sensors

Unique system design allows to fly with extremely low surface-to-sensor clearance starting from just couple of dozens of centimeters. If the sensor will touch the ground or obstacle/vegetation that will not lead to the drone crash. That capability is extremely important for searching for small UXO items over the fields with vegetation.

Self-foldable sensor mount allows easy take-off and landing without excess requirements for drone operator qualification as it is for magnetic sensors on suspension cords.

System variants

MagNIMBUS comes in two possible configurations:

• Gradiometer. This configuration simplifies data processing and makes magnetometer base station not necessary. Additional benefit – gradiometer makes possible magnetic surveys in proximity to the sources of EM fields like powerlines.
• Configuration with single sensor with foldable mount. Detection capabilities are the same as for gradiometer setup, but requires more experienced specialists for data processing, magnetometer base station is recommended in some cases.
  

Main components of the system

• Recommended drone: DJI M400/M350 RTK/M300 RTK. Standard kit comes with all mountings/cables for these drones, sets for other types of drones, including Pixhawk-based, are available by request.
• Foldable mount with build-in QuSpin QTFM Gen-2 magnetic field sensor.
• Mast with QuSpin QTFM Gen-2 sensor for vertical gradiometer configuration.
• SkyHub onboard computer – acts as datalogger for magnetic field sensors and implements terrain following mode for DJI drones.
• Altimeter (laser or radar).
• UgCS Expert flight planning/management software.

Recommended software for data processing

• for in-field and quick processing: GeoHammer Pro
• for large-scale projects and complex processing: Seequent Oasis montaj

UXO/landmines detection note

The system is capable to detect a range of items starting from hand grenades (the estimated sensor-target distance for detecting an object such as the F1 hand grenade is 0.5 m) till big UXO like aerial bombs at the distance of few meters.

While magnetometers can detect some types of landmines (for example M15, M6, TM-62M anti-tank mines; M16, PROM-1, OZM-3, OZM-4, OZM-72 anti-personnel mines and similar types with considerable amounts of ferrous metal), landmines search is not a direct application of magnetometers as they can’t detect most types of modern landmines. That means that the system never should be used to confirm absence of landmines (and small ordnance) in certain area but it can be valuable asset during Non-Technical Survey (NTS) or Technical Survey (TS) to confirm presence of UXO/landmines with considerable amount of ferrous metals.

Ordering

As MagNIMBUS is very versatile customizable magnetometer system, it may require different components to be used with particular drone. Also, different configurations available. Please request the quote to get tailored specification for equipment, software and services.
